ipad and iphone detection nginx module

mesouug commented 6 years ago

Good day.

I've tried both trie and pattern (lite version) for nginx and it seems that plugin doesn't detect difference between ipad and iphone (tried on real devices) even though it clearly states which is which in user agent. I've used nginx config from example. Please let me know if this is expected behavior.

Thanks.

User agents:

Mozilla/5.0 (iPad; CPU OS 11_2_6 like Mac OS X) AppleWebKit/604.5.6 (KHTML, like Gecko) Version/11.0 Mobile/15D100 Safari/604.1
Mozilla/5.0 (iPhone; CPU iPhone OS 10_3 like Mac OS X) AppleWebKit/602.1.50 (KHTML, like Gecko) CriOS/56.0.2924.75 Mobile/14E5239e Safari/602.1

Part of nginx config:

    ## Do a single User-Agent match for device information ##
    51D_match_single x-device HardwareName,BrowserName,PlatformName;

    ## Do a multiple HTTP header match for IsMobile, IsTablet and IsSmartphone ##
    51D_match_all x-mobile IsMobile;
    51D_match_all x-tablet IsTablet;
    51D_match_all x-smartphone IsSmartPhone;

    ## Do a multiple HTTP header match for match metrics ##
    51D_match_all x-metrics DeviceId,Method,Difference,Rank;

    ## Add to response headers for easy viewing. ##
    add_header x-device $http_x_device;
    add_header x-mobile $http_x_mobile;
    add_header x-tablet $http_x_tablet;
    add_header x-smartphone $http_x_smartphone;
    add_header x-metrics $http_x_metrics;

With Lite you don't have access to the following properties that are going to indicate a refined result in this instance.

IsTablet, IsSmartPhone, HardwareName

IsMobile will indicate if the device's primary data connection is wireless and the device is designed to operate mostly by battery power. IsSmartPhone and IsTablet can then be used to separate these into tablets, etc.

Apple intentionally obfuscates device identifier information within User-Agents. As a result, the properties you are are able to to return as a result with Lite will be the same for iPad and iPhone.
